hi, another problem:(this is really hard for me to explain in English, cause it's quite complex and "multi-layered"):

in my program (artificial neuronal network) I have lots of calculations, and a couple of menus to interrupt, load, and restart the program.Now, after some (10-20) minutes of calculation (auto learning) a strange thing is happening:

- the nxt screen is kind of flickering, and the system menu seems to appear (in a sort of "see-through" or "over-laid" way), which even overlaps my own menus;

- among all the figures of my numbers or my menus you can recognize fragments of the system menu with the check button (hook) and the abort button (X), which appear and again disappear;

- independent of what button you are actually pressing, the program doesn't react to my own menus (getkey/readkey functions), but the program reacts to the built-in menu function (check or abort)

- after you have pressed any button, an other system menu is overlaid to my screen, now you can recognize fragments of the nxt system file menu (3 symbols: left: the "TRY_ME"/Lego head, middle: "MY_FILES"/disk symbols, right: "NXT_PROGRAM"/sqare symbols with arrow)

- if you press any button again, you may see that my program was still running in the background, and maybe you can also watch it terminating (my self-programmed "END" screen appearing).

try to train the net with a more complex patterns, such as:in---out 000--11100--10010--01110--00001--10101--11011--01111--00(this includes some hard to calculate XOR conditions so it will run for a longer time).

train it 1x manually.when the last input (111) has been trained, finally there is a long low tone. then choose "autom" (press right nxt button),so now there will be up to 2000 cycles of automized 8-pattern-training.

if you start the program in debug mode (USB) with remote screen , you may watch

1st, the remote screen to freeze2nd, the nxt screen to flicker like reported above3rd, maybe even the nxt program to crash and the nxt to switch off by himself :
